massive parallel processing (MPP)

Massive Parallel Processing (MPP) is a computer architecture of parallel computers used in technical and scientific applications. In MPP processing, each of the numerous processors executes a part of the program. It has its own resources and operates with its own operating system.

In some implementations, the processors access their own hard disks, while others have built a disk pool. The processors communicate with each other by exchanging messages. Therefore, development is focused on the interconnection technology and topology between the processors, which are present in large numbers.

In Massive Parallel Processing, all processors - which can be several thousand - run in parallel and execute a single program. There are a wide variety of technical approaches to MPP processing. These approaches differ in how the individual processors communicate with the memories, or whether all processors execute the same or different instruction sets, such as Single Instruction Multiple Data( SIMD) or Multiple Instruction Multiple Data( MIMD). Furthermore, parallel computers differ in whether they operate with symmetrical or asymmetrical multiprocessors.
